ThinkGeek has a truly awesome-looking Hydrodynamic Building Set for sale. At $90, it’s a bit pricey for a toy, but can you put a price on your kids’ education? And be honest, fellow GeekDads: Wasn’t one of the reasons you had kids in the first place to have an excuse to buy things like this?
(Confidential to my wife: Ignore the last question. I only want this for the kids. Really.)
